Its interrupting capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — the IEC 60947-2 figure is the one that governs industrial panel coordination where fault current may exceed residential limits.
The IP20 protection class (with connected conductors) means it belongs inside a panel or distribution board — not in a washdown or outdoor location.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
